I normally bowl the conventional way hand back or slightly to the side. Now when I don't get the finish I want doing that due to the conditions I go to what I would call my spinning shot hand more over the top. Now I do get a lot more reaction doing that maybe because I don't have a lot of revs the normal way and I seem to get much more reaction when I spin it. My main question is can I drill the ball for a spinning shot would it be a lot different to my conventional drilling I don't mind giving it a go on one of the balls I don't use a lot and would I use a weak or strong ball to do this. Thanks for any replies.
